Taking a family on safari is an excellent plan and South Africa has a very big range of options and accommodation plans to suit. Some of the smaller safari camps will have options where you can take over the whole camp making it exclusive for your family. This gives you the flexibility to be in or out of camp when it suits everyone or part of the family. Many of the camps also have family rooms which generally accommodate 4 people. Destinations like Sun City and Durban are all about family holidays so you wont find it hard to keep everyone entertained. Another factor to consider for South Africa is there are a number of World class sporting events and musical shows that happen frequently here so you could always try and incorporate those into your holiday plans.
